It's somewhere within this glorious, yet depressing document.
I say depressing, because it debunks absolutely ever fact I thought I knew about terminal ballistics. And that 7.62x39 is actually a good round against infantry (in wounding potential, exactly what I used to slam it for), and how fragmentation and yawing not only are similar in effect, but that the effect is actually minimal and not particularly contributing to lethality (but possibly to 'stopping power').

The quote in question:

Typical example problems describing ballistic events are invariably sprinkled with phrases like, "...neglecting air resistance...", "...assuming perfectly elastic (or rigid) bodies...", and "...a collison between perfectly plastic bodies...". Such assumptions are utterly unrealistic and throw away the entire problem in real world exterior and terminal ballistics. One could more sensibly neglect gravity than air resistance! The acceleration due to gravity is only 32.174 ft/s2, but the (negative) acceleration due to air resistance is on the order of 1700 ft/s2 or more for high velocity rifle bullets. The equations of motion governing ballistic flight of projectiles are a set of highly complex, coupled second order differential equations that have no analytical solution, so the textbook manufacturers don't want to discuss it. Its easier to give the student a false impression of reality with a problem that is simply solved.

And that's why I'll never go into gunsmithing or anything involving ballistics. I didn't understand 70% of that article.

- You sure you want to keep the M9 and some of the GLOCK models? Wouldn't the higher-capacity Five-seveN or the higher-power USP's and M1911A1's supersede them?

[Celtic Colonies]

Here is a question. In strait-pull bolt action rifles, how is the bolt locked into place when firing? Most rifles of the age use a rotating bolt that you manually slide into the locked position. But a strait pull has no such thing. So how does it lock?

Basically they use a 2 part bolt assembly, not entirely unlike a contemporary bolt carrier+bolt. The part that you pull straight back is connected via camming lugs to the bolt proper to effect the rotation.

A few types used a different system based on a wedge that locks the bolt rather than rotating it to engage conventional lugs, but it's still essentially a 2 part system - the bolt handle first lifts the wedge out the way then draws back the bolt.

[Coltarin]

Would adopting the Five seveN be a good choice? If so how about making it full auto, because the 5.7mm has a low recoil and would handle better than a 9mm Luger, right?

wat

K31 is rotating bolt...

You pull it back, and the bolt has cam tracks that force it to rotate.

Hm, that makes sense I guess.

Why doesn't the charging handle on an AK flail around wildly as the bolt rotates?

Answer: it is not directly connected to the rotating portion of the bolt.

Are you telepathic or something? I was originally asking it because I want to make a 60's battle rifle but with a flailing charging handle. I like to design my guns to work well enough but have this one or maybe two minor crazy bits for flavor.

Thanks. That explanation did it for me. Now I know.

Go for it. All you need is the charging handle mounted directly to the bolt carrier, or operating rod. M14 effectively does this, as do AK (& derivatives) and L85. Keeps it mechanically simple (compared with decoupling the handle to have it non-reciprocating), and is a perfectly valid choice.

[Samozaryadnyastan]

5.7mm is widely believed ITT to be an unsatisfactory cartridge. It's not particularly good at wounding, it's not particularly good at armour penetration. Its only real advantage over 'conventional' handguns would seem to be its ammunition capacity.

So wait. There actually already is an AR/BR that has a flailing handle?

Also, do you think it would pose an issue with accuracy when fired? What about full auto?

There is a LMG of the G11?

[Samozaryadnyastan]

I think it's just a high-capacity magazine and a HBAR.
I'm not sure the G11 mechanism is capable of sustaining fully-automatic fire at 2100rpm, because of the heating and related cook-off issues.

I have redone my version of the "SRM shotgun". This was the old version i did last august:

Depends what you mean by "flail". The above eg's all have it move back and forth in a straight line as the action cycles, but it doesn't deviate from that axial movement of 90-120mm or so, and they're all mounted in locations where it doesn't actively interfere with normal use of the rifle (apart from restricting left handed use in some cases). Para posted a fairly in-depth video of the M14 action a week or two ago, you might want to look at that for an idea of what's going on.

Derivatives of the M14 are used as Designated Marksman Rifles so I'm sure accuracy in semi-auto is unaffected. In full auto, a little extra mass moving back and forward isn't going to make much difference either I'm sure.

can you suggest a better pistol then I know that the 10mm Auto is ok with power but the recoil is like a kicking mule

[Samozaryadnyastan]

Beretta M9 has a fifteen-round magazine, and an easily-acquired cartridge, the 9mm Parabellum/NATO.
However, if you're after power, you may want to look into the .40S&W, which is a 10mm auto shortened to control recoil.

Apparently, the semi-automatic SVD is more accurate than the bolt-action M24, for reference. So accuracy of a rifle must depend on manufacturing standards and tolerances within, but it's still a surprising concept.

It actually is pretty good @ armor penetration, when compared to FMJ rounds.

Good lord please don't even mention the Beretta or the 9mm NATO the only thing that's good for is target shooting.
The .40 S&W sounds promising but I've also been eying the .357 SIG but I'm also looking for a balance between recoil force and power because what ever pistol I adopt it will have a full auto selection

1) .40 Short and Wimpy.
2) .357 SIG worst .357.

10x31mm Magnum a man's cartridge.

Or if you want to be srs: 7.92mm VBR is better. It has AP loads and can defeat CRISAT while retaining the power of "full sized" handgun cartridges.

Well, imagine something like a mauser rifle. But fired at full auto with the charging handle being cycled together with the bold just like in manual mode but faster. I imagine the noise would be something to be heard.

the .375 has a max muzzle velocity of 1430 ft/s and leaves a 6 in permanent cavity volume

also holy crap the 7.92 has a foot of penetration! good choice sir good choice will look into it

It doesn't change the fact that the M9 isn't a very well-made gun, at least in my experience. I've served in the USCG with one of the Law Enforcement detachments.
Throughout basic and A school I learned to despise the M9. The magazine springs failed more often than anybody would like to admit in the Pentagon (apparently the Baretta-made mags don't have this problem), but the big thing I had to contend with was that no matter how careful I was the damn barrels eventually started rusting suspiciously fast. Never dunked a pistol, always maintained them, but they still kept rusting. The armory crew almost didn't believe me until I I showed them an activity log and proved that we weren't wading across the beach. I finally became so fed up with the situation that I went to my CO, got a list of approved sidearms, and bought my self a H&K USP semicompact in .45ACP.

Fortunately about 3/4 of the way through my term the USCG adopted the SIG 229 in .40S&W. Fantastic weapon that is, wish they would have adopted it sooner while I served.

[Samozaryadnyastan]

The barrel rusting could have been something to do with how most of the barrel is exposed by the slide.
But why weren't Beretta handguns being issued with Beretta magazines, that's what I'd like to know.

Rubbish, 9mm Para works just as well as any of the other pistol cartridges.

What you really want is a large frame psitol (be it 1911, SIG, glock or USP based) chambered in 9x23mm Win with VBR style ammo.

or just say screw it and use a coonan or grizzly in proper .357 magnum


Samozaryadnyastan: The LMG-11 actually a different three chamber revolver mechanism and the PDW-11 use yet another (falling breach). Of course the LMG-11 and PDW-11 never got beyond the wooden mockup stage.
